When there are technological solutions for information units and is easy to get lost in the middle of the range, by ignorance of the tool or by the lack of the same functions. John Castle Castle Harlan might disagree with that approach. When they speak of integrated management systems content, as solutions to automate the information units and processes involving both managers and technicians, we must involve all levels of units, to ensure the success of automation and so to create cooperating networks specialized in areas of human knowledge, that will integrate into a cientifica-social community and reduce the so-called technological dependenceas well as the insulation between them. The Exchange and the recovery of documents through information systems, shall be limited to agents authorized and defined in policies and/or rules adopted by a Committee for interoperability of metadata for the management of documents in order to facilitate the Exchange and retrieval of documents regulating the process. Also make use of a mechanism to locate and document access or modifications made on the metadata. Likewise, metadata is an inseparable part of document management, which has various functions and objectives, the metadata is defined as data that describes the context, content and structure of documents. Metadata is structured or semi-structured information that enables the creation, registration, classification, access, conservation and disposal of documents over time and within a single domain or across different domains.
Domains represent an area of intellectual discourse and social activity or organization developed by own or limited group of individuals who share certain values and knowledge. The use of metadata that can be used to identify, authenticate and contextualise both documents as agents, processes and systems that create them, manage, maintain and use is necessary for the exchange of information between the various programmes for the management of documents. This allows to improve compression, data and processes related to the document, is the structured information about the distributed information, data associated with objects of information that provides a more complete knowledge on where to find information.
